If you just installed Windows and formatted your drive I would assume that you don't have any significant data on the drive you're concerned with.
Personally, I would say the easiest way to fix this is just re-install windows and re-format the drive to the size you want. 20 Minutes of work, and you do not have to buy any new software.
When you format just make sure you delete the existing partitions. Create the new partition and make sure you have selected the full capacity of the drive, less 8MB. IE: 250,000MB -8MB = 249,092MB assuming that your drive holds 250,000MB which it won't.
